Chopped off 40Gb and installed Windows 7 X64, runs like a dream. Got my GPU stable to 750, and have been playing GTA4 for a few hours at 3.85Ghz same voltage. Much more and it bombs out with heavy CPU load.

GTA4 Benchmark, later I will try the same settings in Vista. Loading the ATI drivers causes the system to hardlock during powerplay transitions for me, anyone else have this problem? I can use the Windows Update Drivers and they work OK. And the Overdrive in CCC always claims the overclock fails, even at stock settings?!
